WHAT IS MMI?/Interaction between man and machinevsHigh Severity/ Usually fatal/creative thinking. custom solutions. 2creative thinking. custom solutions. 2
High Severity/OSHA Stats (fork trucks):– 85 fatalities per year– 34,900 serious injuries per year– 36% of fork truck fatalities involved apedestriancreative thinking. custom solutions. 3creative thinking. custom solutions. 3
MMI Objective//Evaluate / identify MMI hazardsDocument existing controls– Risk rank hazards/Recommend additional controls– Risk rank hazards/Establish a consistent process to assess andcontrol MMI risk.creative thinking. custom solutions. 4creative thinking. custom solutions. 4
MMI Benefits/Engineering Controls– Improve segregation between man and machine– Physical barriers– Consistency in physical standards/Administrative Controls / Warning– Improve alert/awareness of mobile equipment– Training and communication– Warning signs, lights, alarms, etc./PPE– Improve visibility of pedestrianscreative thinking. custom solutions. 5creative thinking. custom solutions. 5

Recommended Control MeasuresRecommended Additional Control MeasuresControl Methods and ReliabilityA. Engineering Controls(fully effective to eliminate or mitigate hazard or risk)B. Administrative Contols(partially effective to mitigate hazard or risk)C. Warning Systems and Work Practices(complement to engineering and/or administrativecontrols but ineffective independently to mitigate hazardor risk)D. Training and/or PPE(complement to engineering and/or administrativecontrols but ineffective independently to mitigate hazardor C.3C.4C.5D.1D.2D.3D.4D.5Examples of Risk Reduction MeasuresRedesign process or task to eliminate MM interfaceUse alternative material-handling methods (i.e. conveyors, robots)Reroute mobile equipment and pedestrian paths to eliminate MM interfaceRelocate or install pedestrian or equipment doorsGovern speed of mobile equipment to / 5 mphInstall physical barriers to segregate pedestrians from mobile equipmentInstall one-way spring-loaded gates at pedestrian crossingsEquip mobile equipment with interlocked seat belts or audible alarmsEstablish and mark safe traffic control patternsInstall mirrors at blind spots and intersectionsInstall front and back mounted cameras on mobile equipmentInstall laser light on mast of lift trucks to guide forksEstablish a "halo rule" that requires mobile equipment to be shut off when within 5 feet of unprotected pedestriansInstall PSDI warning lights prior to pedestrians entering the path of travelEquip mobile equipment with audible alarms, lights, beacons, strobesEstablish rule to sound horn at intersections and blind spotsInstall blue lights on mobile equipment (front and back)Install signs at blind spots and intersectionsProvide mobile equipment operator trainingDevelop and implement a pedestrian training package (onboarding and routine)Follow up training regarding use of impact sensorsEstablish a rule to differentiate the status of pedestrians by hard-hat colorProcure and implement the use of reflective/high-visibility garments on all personnelcreative thinking. custom solutions. 8creative thinking. custom solutions. 8
Safety and Health Risk Definitions/Severity: How bad will someone get hurt/Probability (or frequency): How often does activity occur/Control Modifier (or likelihood): How effective are existing controls– Considering controls: engineering, administrative and PPE/Risk Rate: The numerical value of risk determined by multiplyingSeverity X Probability X Control Modifier.– Different risk matrix can be used– Rank before and after assessmentcreative thinking. custom solutions. 9creative thinking. custom solutions. 9
